3/4 divided by what equals 4/9?

Here we will show you how to calculate "what" in this sentence: "3/4 divided by what equals 4/9?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

(3/4) / x = (4/9)

To solve this equation, we want x alone so we start by multiplying x on both sides like this:

((3/4) / x)x = (4/9)x

Which equals:

(3/4) = (4/9)x

Then we divide each side by 4/9 to like this:

(3/4) / (4/9) = ((4/9)x) / (4/9)

(3/4) / (4/9) is 1 11/16 and ((4/9)x) / (4/9) leaves x which means we end up with x = 1 11/16. Therefore, the answer to "3/4 divided by what equals 4/9?" is as follows:

1 11/16

It is always good to double-check your math to make sure you did it right. When we entered 1 11/16 for x in this equation (3/4) / x = (4/9), we get the following true equation which means our math is correct.

(3/4) / (1 11/16) = (4/9)
